Abstract

Ved en fremgangsmåte til kompensasjon av videobildebevegelse utledes en rekke bevegelsesvektorer ved teknikker som fasekorrelasjon mellom par av bilder. For å danne et sett av bevegelsesvektorer som kan benyttes til å definere hovedsakelig alle bevegelser i et inngangsbilde, utledes sett av vektorer fra sammenlig-ning med foregående og påfølgende bilder og blir deretter kombinert for å danne et sett av vektorer for tilordning til et inngangsbilde. Straks et sett av vektorer er blitt utledet, tilordnes de inn-gangsbildet hvorfra de kan projiseres for å produsere et ønsket utgangsbilde. Vektorene er tilordnet individuelle elementområder i bildet og visse elementer har tilordnet to eller flere vektorer.In a method of compensating for video image motion, a number of motion vectors are derived by techniques such as phase correlation between pairs of images. To form a set of motion vectors that can be used to define substantially all motions in an input image, sets of vectors are derived from comparison with previous and subsequent images and are then combined to form a set of vectors for assignment to an input image. Once a set of vectors has been derived, they are assigned the input image from which they can be projected to produce a desired output image. The vectors are assigned individual element areas in the image and certain elements have assigned two or more vectors.
